Hello there, I understand your concern for your relative. Inzofresh is a medicine used to help people with sleeping difficulty. It contains a medicine called Zolpidem. Zolpidem does not go well with alcohol. As zolpidem is already a Central Nervous system depressant taking it along with alcohol can be harmful. In fact if alcohol is consumed in the evening then that night one should not take inzofresh. Although nothing fatal can happen to the person who takes both but it definitely increases the chances of severe CNS depression and patient s chances of sleep walking and doing unintentional things in sleep increases. So please ask your relative to not take inzofresh while still taking alcohol. Hope this helps. Take care.
